Kate Moss 'joined at hip with toyboy lover'

Kate Moss and her rumored boyfriend Count Nikolai von Bismarck are apparently joined at the hip.

The supermodel and Nikolai were first linked in October (15), and it was even reported he was living in the basement of 42-year-old Kate's London home. While either has yet to comment on the alleged romance, the pair recently holidayed together in Brazil. During the trip they were snapped holding hands, and sources close to them say the romance is really hotting up.

"They are very much joined at the hip at the moment, with Kate demonstrating a devotion unseen since the early days of her relationship with Jamie (Hince, estranged husband)," the insider smiled to Britain's Grazia magazine.

Kate's alleged relationship with Nikolai, 28, came about not long after reports surfaced that she'd split from Jamie, to whom she had been married for four years. Both Kate and Kills frontman Jamie have remained tight-lipped on the rumored end of their marriage though.

"It's unlikely Jamie will appreciate such a public display of affection from Kate and Nik, but as far as Kate is concerned it's none of his business," the source said. "Her romance is a welcome distraction from her pending divorce - she's fallen hard for Nik and doesn't care who knows."

As well as their recent holiday, insiders reveal Kate and Nikolai could soon collaborate on a book project. Nikolai is a keen photographer, previously snapping Britain's Princess Beatrice for her 18th birthday portrait. But it's Kate who is now apparently inspiring his work.

"Nik has been obsessively taking photos since he was 13 and has been documenting much of his time with Kate," the source explained. "She loves his work and thinks that he's managed to capture a side to her often not seen. They both like the idea of doing something special with his pictures of her, perhaps a coffee-table book. It's fun for them to collaborate."
